This park sits at a natural opening in the Cumberland Mountains that served as one of the earliest gateways to the West for thousands of settlers traveling across the frontier. During the Civil War, Union and Confederate soldiers vied for strategic control of gap, and several forts still exist in the park. Visitors can explore the Hensley Settlement from the early 1900s, a historic community with original, hand-hewn chestnut and oak cabins. Hikers can enjoy underground tours of the park’s impressive caves, as well as more than 85 miles of trails, including routes that lead to unique rock formations and dramatic waterfalls. The four-mile drive to Pinnacle Overlook also offers wonderful views of three states.
